Selected AbstractsGlycated Hemoglobin Levels and Intellectual Activity in an Aged PopulationJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 12 2005Hidenori Amano MHSc Objectives: To examine the association between glycated hemoglobin (GHb) and aspects of daily activities in an elderly population. Design: Cross-sectional population-based survey. Setting: Nangai village, an agricultural community with a population of about 5,000 located in Akita prefecture in the north of Japan. Participants: Nine hundred thirty-five people aged 65 and older. Measurements: GHb percentages, self-reported measures of activities of daily living (ADLs) and instrumental activities of daily living (IADLs), intellectual activity (IA), and social role (SR). Results: An exploratory analysis indicated that nondiabetic subjects in the lowest tertile of GHb tend to have lower IA than those in the middle tertile, if they were aged 70 and older. No consistent association appeared between GHb and ADLs, IADLs, or SR. Linear and logistic regression analyses, controlling for other risk factors, indicated significantly lower IA scores in the low and high GHb tertiles (P<.001 and P=.04, respectively) than in the middle in nondiabetic subjects aged 70 and older and without stroke history or IADL impairments. The value of GHb related to the maximal IA score was 5.0% to 5.2% as the middle tertile; or 5.2%, assuming a logistic regression model including a squared term with GHb as a continuous variable. A similar relationship was observed in the whole nondiabetic sample aged 70 and older but not in the younger counterpart. Conclusion: There is an inverted U-shaped relationship between GHb and intellectual activity in older people without diabetes mellitus. One possible interpretation is that suboptimal blood glucose could contribute to intellectual inactivity in older people. [source] Can Latin America Protect the Elderly with Non-Contributory Programmes?DEVELOPMENT POLICY REVIEW, Issue 6 2005The Case of Uruguay Coverage of contributory pension programmes has been quite disappointing in Latin America in the aftermath of the reforms. The question thus arises as to whether non-contributory programmes could fill the gap. Uruguay is atypical in this region in that the proportion of the elderly receiving contributory pensions is high, and the incidence of poverty among the aged population is lower than among any other age group. But several observers fear that this situation could deteriorate in the future, because the conditions for accessing the pensions have been significantly tightened in the past decade. This article assesses several options for reforming the existing non-contributory pension programme, and estimates their fiscal cost. [source] Post mortem survey of dental disorders in 349 donkeys from an aged population (2005,2006).EQUINE VETERINARY JOURNAL, Issue 3 2008Part 1: Prevalence of specific dental disorders Summary Reasons for performing study: Donkey dental disorders are being recognised with increased frequency worldwide and have important welfare implications; however, no detailed investigations of dental disorders in donkeys appear to have been published. Objectives: To determine the prevalence of specified dental disorders in donkeys by performing a prospective post mortem study on donkeys that were subjected to euthanasia or died for other reasons at the Donkey Sanctuary, UK. Methods: Post mortem examinations were performed on 349 donkeys over an 18 month period, 2005,2006. The presence and extent of specified dental disorders were recorded and these data analysed to determine their prevalence and common locations. 45Results: A high prevalence (93%) of disorders was noted in the population with a median age of 31 years. In particular, cheek teeth diastemata (85% prevalence) were very common, often associated with advanced periodontal disease. Other disorders observed included missing teeth (in 55.6% of donkeys), displaced teeth (43%), worn teeth (34%), local overgrowths (15%), focal sharp overgrowths (3%) and dental-related soft tissue injuries (8%). Conclusions and potential relevance: Aged donkeys have a high prevalence of significant dental disease, especially cheek teeth diastemata. These findings highlight the importance of routine dental examinations and prophylactic dental treatments to improve the dental health and welfare of donkeys. [source] Japan's never,ending social security reformsINTERNATIONAL SOCIAL SECURITY REVIEW, Issue 4 2002Noriyuki Takayama This paper examines implications of the 2002 population projections for future trends in pension and healthcare costs in Japan. Current redistributive pension and healthcare programmes have resulted in considerably higher per capita income for the aged than the non,aged population. Substantive reforms are needed to lessen the extent of such redistribution, but political considerations have meant that only incremental reforms have been feasible. A start, however, has been made on introducing private initiatives in pensions; and shifting from the command and control model operated by the central government to a contracting model for healthcare.

Non-alcoholic fatty liver disease , a common and benign finding in octogenarian patients. Liver International 2004: 24: 588,594. © Blackwell Munksgaard 2004 Abstract: Background: Non-alcoholic fatty liver disease (NAFLD), a common entity in the general population, has been shown to be linked with insulin resistance and metabolic syndrome. Several of the components of the metabolic syndrome are more common in the aged population. The aims of the current study were to determine in the aged, the prevalence and the clinical presentation of NAFLD, as well as the relation to the underlying metabolic abnormalities. Method: In this prospective study, we evaluated 91 octogenarians with a mean age of 85.56±3.76 years, who were admitted to the rehabilitation departments of a geriatric hospital. Clinical evaluation included: abdominal ultrasound (US), fasting glucose and lipid levels, serum liver enzymes, ferritin, iron and transferrin saturation. Elderly patients with NAFLD were compared with 46 young patients with NAFLD. Results: NAFLD diagnosed by US was a common finding in this aged population, is present in 42/91 patients (46.2%). No significant differences were observed between the patients with or without NAFLD in the following: age, gender, chronic illnesses, anthropometric parameters, lipid profile, fasting glucose levels, metabolic syndrome prevalence, serum levels of transaminases, ferritin and iron. Young patients with NAFLD had significantly higher serum levels of triglycerides and a significantly higher prevalence of glucose intolerance, obesity and the metabolic syndrome compared with the elderly patients with NAFLD. Conclusions: NAFLD was a common finding in our group of elderly patients and the prevalence was higher than reported in the general population. In contrast to the well-described association between the metabolic syndrome and NAFLD in the general population, we did not find this association in the aged group. In addition, none of the patients had stigmata of advanced liver disease. These data suggest that NAFLD is a common and benign finding in the elderly population, but is not associated with the metabolic syndrome. [source] Population structure and establishment of the threatened long-lived perennial Scorzonera humilis in relation to environmentJOURNAL OF APPLIED ECOLOGY, Issue 2 2002Guy Colling Summary 1The intensification of agriculture has resulted in the decline of many plant species of nutrient-poor wet grasslands. At some sites local populations of long-lived characteristic species have persisted and might benefit from recent extensification schemes. However, little is known about the population biology of these plants, and the prospects for the populations are uncertain. 2We studied the population structure and establishment of the long-lived Scorzonera humilis in 23 populations in Luxembourg and neighbouring Belgium. Two types of populations could be distinguished according to their population structure: regenerating populations, with a high proportion of plants with only one or a few rosettes, and aged populations, with a low proportion of small, young plants but a high proportion of individuals with many rosettes. The total density of Scorzonera individuals was higher in regenerating than in aged populations. 3Within sites, S. humilis was restricted to more open and nutrient-poor patches. The composition of the vegetation in plots where S. humilis was present was significantly different from that of plots without the species, indicating that S. humilis is restricted to particular microhabitats. 4In multiple regression analyses, environmental variables explained a large part of the variation in the total density of genets, the density of genets of different size and the density of rosettes. The main variables of influence were site productivity and soil moisture. With increasing productivity and decreasing soil moisture the proportion of small genets decreased and that of large genets increased. Increased productivity had contrasting effects at the genet and ramet (rosette) levels. While genet density decreased, ramet density increased, indicating that if a site is fertilized, recruitment of new genets and survival of genets is reduced, but growth of surviving genets is increased. 5The results of a sowing experiment indicated that an aged population structure was due to a lack of recruitment. The number of seeds that germinated and the proportion of seedlings that survived until the next summer were positively correlated with soil moisture and negatively with productivity. Germination rate and establishment success were significantly higher in Molinion grassland than in the Calthion grasslands. 6The results suggest that for long-lived species the size and number of populations may not be good indicators of the status of a species. In S. humilis large populations (> 1000 genets) still exist, but all are of the aged type. In order to preserve existing populations of S. humilis, management should aim to reduce productivity and increase soil moisture. [source] Survival and expansion: migrants in Greek rural regionsPOPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 6 2008Charalambos Kasimis Abstract Migratory movements towards southern Europe have increased considerably in the past 20 years. An important aspect of this process is connected to the agricultural sector and rural regions , a development connected to agriculture's particular weight in the economies and societies of all southern European countries. However, their role is not restricted to agriculture. They are also related to non-agricultural economic activities and the overall support of aged populations, especially in marginal or mountainous rural areas. This paper draws on the qualitative and quantitative findings of two research projects carried out in three exemplar rural regions of Greece and over two different periods: 2000,2002 and 2004,2006. The aim of the research was the empirical investigation of the economic and social implications of the settlement and employment of migrant labour in rural Greece. The paper moves from the presentation of the theoretical and methodological framework to the presentation of the main findings for each period of the research. The socioeconomic implications of migrant employment and settlement in the regions studied are revealed in the light of the recent Common Agricultural Policy changes, and the changes following the implementation of ,regularisation programmes'. Additionally, the characteristics of migration trends in these regions are identified and the formation of new migrant social groups, with different prospects of social integration and mobility, is revealed.
